It took about an hour for firefighters to knock down the blaze, according to Oswego County 911.

The two-story house is L-shaped. The wing containing the stove was substantially damaged, Euler said.

Heilveil had installed the stove himself on Monday and had it inspected, Euler said. Oswego County fire investigators are exploring whether a flaw in the installation may have caused the fire, he said.

New Haven, Sandy Creek, Scriba, Parish, Hastings and Pulaski volunteers responded with Cody on standby. State police and McFee ambulance also responded.
